CHRISTIAN ANDERSEN, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN FILTERS.

Specification forming part of Lcttcrs Patent No. 151,339, dated May 26, 1874 application led May 14, 1874.

To all whom fit may concern:

Be it known that I, CHRISTIAN ANDEnsEN, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Filters, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which Figure l represents a vertical section of this invention. Fig. 2 is a horizontal section of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a lining of cloth, felt, or other absorbent material on the solid sides of a filtering-vessel, which is iilled with bone-black or other iiltering material, and the top or bottom, or both of which are perforated, while the liquid to be filtered is introduced through a pipe with a rose-head, in such a manner that by the absorbent lining the formation of channels through the ltering material close to the sides of the ltering-vessel is prevented, and the liquid to be liltered is brought in intimate contact with the filtering material.

In the drawing, the letter A designates a vessel made of sheet metal or any other suitable material, in any desirable form or shape. The sides a a of this vessel are solid, but its head b (or its bottoni) is perforated, and over this perforated head is placed a cap, B, so that the liquid to be ltered passes through the perforations in the head b into the space un der the cap B, whence it discharges through the pipe c. The liquid is admitted t the liltering-vessel through a pipe, d, which terminates in a rose-head, e, situated in the interior of the vessel A, and the solid sides of this vessel are lined on their inner surfaces with layers f of cloth, felt, or other absorbent material. l

The vessel A is packed with bone-black or other filtering material, and if the sides ofsaid vessel are not lined with an absorbent material the liquid to be filtered, on being admitted to the vessel A, forms `channels through the iiltering material close to the sides of said vessel, and a large percentage of the liquid escapes from the filtering-vessel Without having` come in contact with the filtering material, 'and consequently without having been deprived of the impurities mixed with it. This disadvantage I have successfully obviated by lining the sides of the filtering-vessel with an absorbent material, and my experience shows that by the application of such lining the formation of channels through the iilterin g material is successfully avoided, and the liquid to be iltered is prevented from passing through the ltering material in the vessel A without coming in intimate contact with the same, so that said liquid, as it discharges from the tiltering-vessel, is deprived of the impurities which had been mixed with it.

That I claim as new, and desire to secure by Letters Patent, is-

The arrangement of a lining, f, of cloth, felt, or other absorbent material on the Asolid sides of a filtering-vessel, A, which is provided with perforations in its head or bottom, or in both, and to which the liquid to be iiltered is admitted through a pipe, d, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
